Understanding the biodiversity consequences of habitat change: the value of secondary and plantation forests for neotropical dung beetles
1. Secondary and plantation forests are becoming increasingly widespread in the tropics. A recent meta-analysis on the impacts of land-use change on tropical forest dung beetles concluded thatExpand
The cost-effectiveness of biodiversity surveys in tropical forests.
This work presents a generic and novel framework for identifying high-performance indicator taxa that combine practical feasibility and ecological value, and illustrates the approach using a large-scale assessment of 14 different higher taxa across three forest types in the Brazilian Amazon. Expand
Improving the design and management of forest strips in human-dominated tropical landscapes: a field test on Amazonian dung beetles
Summary 1. The future of tropical forest species depends in part on their ability to survive in human-modified landscapes. Forest strips present a priority area for biodiversity research because theyExpand
Changes in the dynamics of functional groups in communities of dung beetles in Atlantic forest fragments adjacent to transgenic maize crops
The observed impact of transgenic crops on functional group dynamics within dung beetle communities could potentially lead to impaired capacity for feces removal, seed dispersal, edaphic aeration, and incorporation of organic matter in the soil in these areas, as such ecosystem services are not performed by the dominant functional group (i.e., dwellers).

Spatial Patterns of Movement of Dung Beetle Species in a Tropical Forest Suggest a New Trap Spacing for Dung Beetle Biodiversity Studies
Dung beetle species with different sets of ecological traits may differ in their dispersal ability, so a new minimum distance of 100 m between pairs of traps is suggested to minimize interference between baited pitfall traps for sampling copronecrophagous Scarabaeinae dung beetles. Expand
Attractivity of omnivore, carnivore and herbivore mammalian dung to Scarabaeinae (Coleoptera, Scarabaeidae) in a tropical Atlantic rainforest remnant
In this study, performed in a remnant of Brazilian Atlantic Forest, three types of dung from animals with distinct alimentary habits were utilized, in order to verify possible differences ofExpand
The Role of Body Size and Shape in Understanding Competitive Interactions within a Community of Neotropical Dung Beetles
Dung beetles provide a useful model for understanding the structuring of ecological communities and the role of competition based on their size and morphology, and there were differences in body size, but also in body shape, suggesting a reduction in their level of competition. Expand
Neutralizing antibodies to human and simian adenoviruses in humans and New-World monkeys.
Surprisingly, sera from some New-World monkey species were able to neutralize AdC6 and/or AdC68, the best-studied vector of adenovirus, and the implications for the development of Ad-vector vaccines are discussed in detail. Expand
The night and day of dung beetles (Coleoptera, Scarabaeidae) in the Serra do Japi, Brazil: elytra colour related to daily activity
Among the colourful diurnal dung beetles, measure of body length of each species shows that development of bright colouring was more often found in medium to large species, which suggests that colouring evolved as a response to intraspecific pressures, important in agonistic encounters among males.
